A 12x12 inch paver is one square foot. So you would need 240 square feet.
190
In theory the answer is 240 tiles but this assumes that the area is "well behaved" and, if not, that you are prepared to use all the offcuts to fill bits in mosaic-style. A shape which in 17 inches wide, for example, will require a lot more pavers.
68
80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
To determine how many 6x9 pavers are needed to cover 190 square feet, first calculate the area of one paver. The area of a 6x9 paver is 0.5 square feet (6 inches = 0.5 feet, 9 inches = 0.75 feet; thus, 0.5 x 0.75 = 0.375 square feet). Next, divide the total area to be covered by the area of one paver: 190 square feet ÷ 0.375 square feet per paver = approximately 506.67. Therefore, you would need about 507 pavers to cover 190 square feet, rounding up to the nearest whole number.
12" x 12" = 1 square foot, so you need 452 of them.

it will cover a 12x12 room
195 12 inches x 12 inches is 1 square foot
You would need 320 pavers to cover 160 square feet with 6x9 pavers, assuming each paver covers 0.5 square feet.
144.63 pavers
Any reason why it shouldn't be 220, apart from the shape of the area?
To determine how many 12x12 tiles are needed for a 54 square foot area, first calculate the area of one tile. A 12x12 tile is 1 square foot (since 12 inches is 1 foot). Therefore, to cover 54 square feet, you would need 54 tiles, as each tile covers exactly 1 square foot.
144 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
4.5 pavers will cover 1 sq foot. So 4.5 x 360 =1620 pavers
